1. A method for sampling a core, the method comprising:
- providing a corer with an outer wall;
providing a plurality of impregnation tubes between an inner wall and the outer wall of the corer, wherein the impregnation tubes are disposed parallel to a central axis of the corer;
extracting a core sample using the corer; and
in-situ stabilizing, within the corer, unconsolidated sediment in the core sample, wherein the step of stabilizing unconsolidated sediment comprises impregnating the core sample with a resin.

Abstract
Apparatus and method for in-situ stabilization of unconsolidated sediment in core samples are disclosed. The core sampling apparatus includes a corer having an inner wall, an outer wall, and a plurality of impregnation tubes disposed between the inner and the outer wall, wherein the impregnation tubes are parallel to a central axis of the corer. The method for sampling a core includes extracting a core sample using a corer, and in-situ stabilizing unconsolidated sediment in the core sample within the corer by impregnating the core sample with a resin. The resin is supplied through a plurality of impregnation tubes disposed between the walls of the corer.
